Oops, sorry Infinisearch. I remember now that when I first saw your link I was too busy to update. Then, it just slipped my mind.

All fixed now. That's a very nice site. I made links to the Model and Texture download pages. If people want to futher explore the resources they offer, they can navigate on the site. Thanks!

Now, I have a question for everyone. Should I include links to downloadable Sound Effects? The PRO would be that it's another highly sought-after resource that I could throw into my list. The CON is that it's not "Visual Arts". Sound effects belong in the "Music and Sound" forum, where people are more likely to look for links regarding them anyway.

They various versions of the 2D tree tutorials address Painter, PSP and Photopaint, including earlier versions. Rather than post all of the variants, here's the main page. Most of the tutes below are on this page as well.
